The AS1359-TT-15_EK_ST is a evaluation board for linear voltage regulators which provides a low-drop, low power integrated voltage regulator with high accuracy for power supply applications. It is designed to operate over a wide input voltage range, from 5V to 15V, and provides an output voltage of 3.3V±2.5% at up to 5A. The board is constructed using a single-sided copper-clad board, which makes it very easy to assemble. The board features an integrated power switch which allows the user to easily switch the power source between the main supply and the secondary supply, and a status LED which indicates when the output is in regulation.

The AS1359-TT-15_EK_ST evaluation board has a wide range of applications, especially in voltage regulators for power supplies, such as in server systems, industrial equipment, and automotive applications. It is also suitable for powering microcontroller systems and providing local voltage regulation for sensitive circuits. Additionally, its high accuracy makes it ideal for precision-regulated power supplies, such as in medical and laboratory equipment.

The working principle behind the AS1359-TT-15_EK_ST evaluation board is based on a linear voltage regulator. Linear voltage regulators are designed to supply a constant output voltage by varying the amount of current it takes from the input power source. The output voltage is set using a voltage divider circuit or a resistive voltage divider potentiometer. When the voltage at the output of the regulator exceeds the setpoint due to an increase in input voltage, the regulator reduces the amount of current it takes, simultaneously reducing the output voltage. Conversely, if the voltage at the output of the regulator is lower than the setpoint due to a decrease in input voltage, the regulator increases the amount of current it takes, simultaneously increasing the output voltage. This process is continually repeated, allowing the output voltage to be regulated to the desired level under varying input voltages.

The AS1359-TT-15_EK_ST evaluation board provides protection against current overload, reverse battery operation, thermal shutdown, and output voltage overshoot. In addition, its high accuracy ensures that the output voltage is maintained, even when the input voltage or load current varies. Thanks to its small form factor and easy-to-use features, it is a perfect solution for powering and controlling low-voltage applications.
